Tocllcvhom it may concern Beat known that l, AUoos'r and" useful Windowdlurtain Fixture, of

which the following is a; specification.

'llhis invention relates to window curtain fixtures especially: designed ion use incon-Q ne ction withthe curtains of street cars and the like. In fixtures ofthis character it is the practice to have members projecting he yond the sidesaot thecurtain for engaging the indow casing so as to hold the curtain atany position to whichit might noved.

One of the objects of the present llliclltion is to simplify and otherwise. improve upon the con truction of the nature used for th s pur tiose, reducing the number oi. parts to the minimum andproviding L -structure which '13: compact; durable and e'liicient and the parts of which can be assembled readily Q in the process of manufacture With the foregoing and other objects in view, which will appear as the description proceeda the invention resides in tlie rcmg binatiori and arrangement of parts and in the details of construction hereinatter described and claimed, itgbeingunderstood, that, wlthin the scope-of what s claimed, changes in the precise embodiment of the 111- vention shown canhe made Without departing from the spirit of the invention.

in the accompanying drawings the preiterred form of the invention has been shown.

Figure is an enlarged section through one of the fixtures, the finger engaging por- 'tion being removed.

Figure 3 an end elevation oi the fixture;

' hlsrure 5 1.8 a perspective 16 of t he"tubuelarshank of the fixture Referring to the figures by characters or reference A designates a window shade having the usual tubular housing B 111 the free transverse edge thereof, this housing containing the fixtures employed for holding the shade at desired positions and which fixture constitutes the presentinvention.

Each of the fixtures in the present ins an e of the angular shank 3.

includes a tubular body, member 1. e2;- C. Hanna, afcitizen ofthe UnitedStates, residing at Reading, in the county of liliddlese z and State oi ll lassachusetts, have invented a new the housing B. This body portlon has a tubular shank 3 extending it'roni one end thereof, said shank being rectangular in cross section and being provided with a cylindrical opening 4: e2;tendhlgv there through Groovesoiareformed in opposed faces of the shanlcdirectly opposite each other. A look nut Gengages the exterior threads the body 1 and is adapted to bind against the end of the housing l3, thus to hold the body 1 against movement after it has been properly adj usted in the housing.

Theangula r shank 3 projects through an angular opening 7 formed in the interniedh ateportion of an elongated yoke 8 and mounted in the end portions or this yoke are bearings 9 on each of which is supported.

a roller 10 provided with parallel annular grooves 11.

,ltfextjending thereintofroni end to end.

Spring wires are fitted loosely within the grcioves 5 and are bent upon themselves so as to fit snugly within the grooves 11 and the two rollers 10, the free ends of these wires projecting into the ends of the bores 14: as shown particularly in lli re 2. Thus it will be seen that the spring wires 15 hold the body 1 and the yoke assembled and nor mally in a predetermined relation and at the same time maintain the friction block 13 in a predetermined position relative to the end lhfinger piece 16 of the usualor any preferred type is extended from that end of the rod 1.2 remote from the block 13 and by pressing thereagainst the rod 12 can be shifted longitudinally soas to move the block 13 toward the shank 3 and at the same timeplace the end portions 0:! the wires 15 under increased tension. When the block is thus shlfted the curtain A can be moved. readily from place to place and when the finger piece is released the block 13 will lOGShlftGCl outwardly by the ends of the spring wires 15 until it trictionally engages the window frame. The yoke 8 and the parts carried thereby can now'be shifted bodily inwardly relative to the body 1 and. the rod-12 in which event those portions of the Wires engaging the grooves 5 Will flex as Will also the end portions of the wires engaging the block 13. By thus mounting the structure so that both the yoke and the block are capable of movement relative to the body although the parts are held by the same spring, the structure is rendered very eflicient in operation because of the ease With which it Will follow any irregular contours. This construction is also advantageous because of the few parts employed, the simplicity of construction, and the readiness with Which the parts can be assembled.

- What is claimed is: V

l. A curtain fixture including a tubular housing having an angular end portion, an actuating rod slidably mounted Within and projecting through the housing, a yoke slidably mounted on said angular portion of the housing, a friction block mounted on one end of the rod, rollers ournaled in the yoke, and a spring straddling the rollers and engaging the housing and block to yieldingly hold both the rollers and the blocks against movement relative to the housing.

1 2. A curtain fixture including a yoke, spaced rollers carried thereby, a tubular body projecting into the yoke and slidably engaged thereby, an actuating rod movably mounted in the. body, a friction block secured thereto and supported between the rollers, and a spring straddling the rollers and engaging the block and body to hold the same yieldingly in a predetermined relation.

3. A curtain fixture including a tubular body, a yoke slidably mounted thereon, an actuating rod extending through the body,

a friction block secured to the rod, rollers carried by the yoke and at opposite sides of the block, and a spring straddling the rollers and engaging the body and block to hold them normally in a predetermined relation, said block being movable relative to those portions of the spring engaging the same.

L The combination with a body having a groove therein, a yoke loosely mounted on the body, and means carried by the yoke for engaging a window frame, a friction block. an actuating rod connected to the friction block and movable relative to the body, of a spring extending loosely within the groove in the body and movably engaging the block to hold the rod, block and body normally in a predetermined relation.

The combination with a body having a grooved end portion, the grooves being disposed in opposite portions oi the body. of a yoke loosely mounted on the body and held against rotation relative thereto, grooved rollers carried by the end portions of the yoke, a friction block, an operating rod movable relative to the body and engaging the block, said block and body pro-- jecting between the rollers, and springs loosely mounted in the grooves in the body and straddling the rollers, said springs being seated in the grooves in the rollers and having their terminals projecting into and slidably engaging opposite ends respectively of the friction block.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
